fi UNirEDjgsrAifE S KNUTE ANBERG; oFoAxLANi), oALiFoRNiA The presentinvention relates to improvements in means for picking .corn and moreparticularly means forvpicking that 4type of corn known as Egyptiancorn, vwhich distinguishes from Indian corn by the fact Jthat the seedsare much smaller and are held in a head resembling somewhat a bunch ofgrapes.

ln its general features, myinvention Vcomprises a corn-stripping means1, a guide means 2 for guiding the heads of yEgyptian corn toward thestripping means, suction .nieans indicated. at 3 for drawingY thec'ornseeds'fand chan fromthestripping meansand 'delivering the same into thehopper where n v`theseed is cleanedand" delivered to sacks whichniay'be"attached to the bottom ofthe Thel device, as shown inthe drawings, is

The ytractor V11', which may be of 'any suittending Vforwardlytherefrom, the brackets being preferably secured Vto the tractor frame`by means of bolts 14 or otherwise.

r Thevforward end of each bracket'is forked and supports four uprights16, lwhich are joined at their upper ends by means of a rectangularframe 17. This fraine supports two ycross pieces 18, forming bearingsfor two longitudinal shafts 19 and 21, one being mounted 2Vsubstantially over the center of the fork, Iwhile rthefotherfis mountedover the edge..Each of the two shafts 19 and 21 carries a sprocket 22and y23 respectively. 'Underneath the forked end ofthe bracket and invertical alignment i 9o i with the two sprocket wheels 22 and23, there Y*are two-other sprocketwheels 24, and va cha-in 261is guided overtherfour sprocket-wheels,

Vthe 'ends ,-ofthechain being fastenedA vtoitlie Vdruni27 arrangedbetween the four Vuprights 16 and guided by the latter by means ofperrespectively. vv'lheupper shaft 19 isfconnected through avv universaljoint 2 9 with the shaft lyfwhich may be operated from the drivers Vforated guide-blocks 28-riding on the uprights row of standing corn.Within the drum, there.

are mounted lthree pairs of brushes 37, the two brushes of each pairbeing madeto revolve in opposite directions. rlhe front ends of thebrushes are tapered, as shown at 88, so that when a head of corn isguided between the two brushes of a'pair, the brushes will grip the headfrom opposite sides and will strip the same of the seeds, throwing theseeds outward against the end faces of the drum.

The structural features of this arrangement may be varied in many waysand are shown in the drawings as comprising a shaft 39 extending intothe drum from one side,the shaft receivino' rotar motion through bevelO'ears b O D 41, an extensible shaft 42, a second set of bevel gears 48and a transverse main drive shaft 44, having the pulley 46 fixedthereto, which pulley receives rotary motion from the tractor mechanismthrough any suitable means. The shaft 39 extends into the drum somewhatbeyond the center line and has two small cages 47 fixed thereto. Each ofthe cages has three radial spokes 48 joui'naled in its wall, and each ofthese spokes carries a brush 37 and isrevolved by means of a bevel gear49 fixed to the spoke and meshing' with a stationary-,bevel gear 5lfixed to a stationary sleeve 52 extending into the drum inconcentricrelation with the shaft 39. Each cage has also fixed theretothree vblades 58 extende ingin a direction diametrically opposite eachspoke 48, and proj ecting from a disc 54 which latter has arms 56extending therefrom for supporting the extension points of the brushes38 as shown Aat 57.

Itwill be seen from this description that when the pulley 46 is rotated,this rotary motion is transmitted through the bevel gears, indicated at48 and 4l, to the shaft 39, which latter causes the cages 47 and withthem the Vbrushes and the blades to revolve withinthe drum. `While thebrushes 37 revolve 4about the axis of the drum, they are also madetorevolve, in opposite directions, on their own axes, due to theengagement of the bevel gears ing forwardly from the forked end of eachi bracket 12 so as to straddle a row of corn and braces 58 connectingthe forward end of each bar 57 with the upper ends of the uprights 16,with suitable guide plates 59 and 6l supported on the braces and thedrum respectively.

Each of the drums is connected through a flexible pipe 62 with a blower63, which creates suction in the drum and draws the seeds and the chafffrom the drum,lto deliver the same through a piper64 into the hopper 66,preferably mounted at the rear end of the tractor.' This hopper iscylindrical in its upper section and the seed and chaff are deliveredinto the same in a tangential direction, so as to whirl in the hopperbefore settling, whereby the cha' is separated from the heavier seedsand blownaway over the edge of the hopper, while the seed is dischargedthrough eitherone of the spouts 67 into a bag suspend-ed therefrom.

The operation of the device will be readily understood from theforegoing description.

The operator of the tractor drives the same so tliateach pair of guides2 straddles a row of corn.v He then, by operation of his hand wheel 33,Vraises or lowers his drum 27 in accordance with the height of the cornto be picked. After having made this adjustment, he advances thetractor, and the heads of the corn are successively guided between thebrushes which, revolving in opposite direc .tions on their own axes andalso revolving on the axis of the drum,'ride.upwardly on the stem ofthe.corn,rdraggingthe upper end forwardly until they reach the head,whereupon they strip the head ofthe seeds, throwingthe seeds against'the`two end walls of the drum to be caught by the blades 53, from Vwhichtheseeds and vwhatever chaffV has been separated with the same are drawnVby suction into the flexible pipe 62 and nally delivered into thehopper 66, where the whirling motion causes the chaff tovbe thrown overthe edge of the hopperwhile the seed is discharged into a sack securedto oneof the spo'uts 67. Two spouts are provided to allow operation tocontinue whilethe sacks are changed.

It will be noted thatthe pairs of brushes 37 swing about the axis of thedrum ina counter-clockwise direction so that each pair of brushes willhave a vertical wiping effect on the head of corn. The outer ends of thefor receiving the head of corn. The brushes Vof each pair rotate inopposite directions and not only remove the seeds from the corn, but

Valso throw the seeds against both sides of the housing where they willdrop upon the vanes 58 and subsequently be carried to the suction pipewhere they will be sucked in and conveyed to the hopper 66.
